 The exception message for asynchronous registered plug-ins is written to a **System Job** table, also known as the [AsyncOperation Table](reference/entities/asyncoperation.md)  which can be viewed in the **System Jobs** area of the web application. No dialog will be displayed to the user. Async plug-ins do not participate in the database transaction that queued them, therefore they cannot cancel the transaction.
 
+### Retry an asynchronous plug-in
+
+With an asynchronous plug-in step, you can re-try when a plug-in fails. This may be due to a network error or some other re-triable error calling an external resource. 
+
+To retry your plug-in, use the [InvalidPluginExecutionException(OperationStatus, Int32, String)](dotnet/api/microsoft.xrm.sdk.invalidpluginexecutionexception.-ctor?view=dynamics-general-ce-9#Microsoft_Xrm_Sdk_InvalidPluginExecutionException__ctor_Microsoft_Xrm_Sdk_OperationStatus_System_Int32_System_String_) constructor using the [OperationStatus Enum](https://docs.microsoft.com/en-us/dotnet/api/microsoft.xrm.sdk.operationstatus?view=dynamics-general-ce-9) `Retry` member value.
+
+When your plug-in throws this type of exception, the asynchronous service will attempt to run your plug-in four times. If it doesn't succeed within four attempts it will fail.
